To all whom it may concern Be it known that I, STANLEY HOBSON,

' .a citizen of the United States, residing at Rockford, in the county of Winnebagoand State of Illinois, have invented certain new and useful Improvements in Warming Ovens, of whichthe following is a specification. V v

ThlS invention relates to. stove construction and more particularly to a, novel warming oven-and construction of a fiexlble sectional closure ordoor therefor. v

Doors for warm ng ovens of various types cept the warming oven space and preclude convenient access thereto for permitting the placing and removal of the articles of; food,

especially in the back portion of the oven which is cutoff by the door when swung to a supposedly open position. Furthermore, closuresor. doors of warming ovens have been unsightly, heavy and; cumbersome in comparison with the service rendered, owing -to'the employment of heavy cast metal parts much out of proportion to their utility.

The present device overcomes the, above objectionsand providesi'a 1193761 closure for warming ovens which is extremely attractive in appearance and may be made to conform to the enameled orfother partsv of the "stove, aswell as being constructed of light sheet metaL'e'asy to manipulate andwhich 1 will move without noiseand remain in any desired adjusted position without iniany tions in contact, together with guide means [as to cause the;

' work w1th ease.

mannerobstructing the warming oven space or preventing free access to the'same for placing or removing food stuff. .The invention also comprehends a. novel door or closure embodying a plurality of sections with meansfor maintaining the sectherefor which permit the closure or sections to be moved without undue friction and without a squeaking noise usually, caused by the movable contact of metalwith metal,

as well as to prevent the door binding.

My invention further provides for adjust ment of the door with reference to the front I opening and walls of .the warming oven so parts to properly fit and,

@Other objects and attendant advantages will be appreciated bythose skilled inthis art when considered-in connection with the ac- V STANLEY n1. fnonsoiv, oi'fnocxronnj, Y'ILLINOIQSQASSIGNOR j'ro 'G EOfD 'nornn c03 as; fi v mmn be b t iinderstjooaf vbyllreferencee to the following lesQliPtion partly broken away and' a section showing an elevated oven and a w'arming'ovenclosure there for constructed in accordance with the invention. 7

A cast metal frame 7 is provided above the oven 5 and includes spaced side members having curved front. ,portlons as shown.

The plate 12 has asurrounding dependingflang'e' .15 substantially corresponding to the depth of the frame 5and closing'the space be, :tween. the top' and bottom walls thereof as seen 'in Fig. 2. The side portions of the frame? are of rlght'angular c-ross-sect on'as distinguished fromthe channel cross-section at the front corresponding to the top" of the frame55 ofthe oven 5, as shown in Fig. 3.

A back plate 16 is secured to the sides 8,
